Description
Technical field
The utility model relates to a kind of clamping tools for thin-wall tube-shaped element processing, belong to field of machining.
Background technique
Thin-wall cylindrical part poor rigidity, processing and part is also easy to produce flexible deformation when clamping seriously affect the processing of part
Precision.The method taken at present is mainly reduced bite, increases semifinishing number, is finally refined to size requirement, this
Not only time-consuming for kind of method, but also when machining allowance is fewer, part is thinner, and difficulty of processing is bigger, is easily deformed, and leads to zero
Part dimension overproof.
Utility model content
Rigid, easily-deformable, unmanageable problem that purpose of the utility model is to solve Thin-wall cylindrical parts, and provide
A kind of clamping tool for thin-wall tube-shaped element processing.
The purpose of this utility model is achieved through the following technical solutions:
A kind of clamping tool for thin-wall tube-shaped element processing of the utility model, including expansion sleeve, retaining ring, swelling body
And elastic ring；
Expansion sleeve is circular ring shape component axially bulk-breaking structure made of equal point of cutting, the outer diameter of expansion sleeve circular ring shape component with
The internal diameter of cylindrical member to be clamped matches, and the inner cavity of expansion sleeve circular ring shape component is the outspreading backwards conical surface, expansion sleeve circular ring shape
The outer wall of component is machined with elastic ring mounting groove, and the front end face of each bulk-breaking of expansion sleeve is extended with forward guide pin；
Retaining ring is the annular element that outer diameter and cylindrical member internal diameter to be clamped match, and the inner hole of retaining ring is threaded hole, lock
The guide groove for being provided with one group of circle distribution in the rear end face of tight ring and radially extending, the distribution of retaining ring rear end face guide groove
Position and the distributing position of guide pin on each bulk-breaking of expansion sleeve match；
The leading portion of swelling body is cylindrical section, and the back segment of swelling body is outspreading backwards conical section, the cone of swelling body conical section
It spends and matches with the taper of the inner cavity conical surface of expansion sleeve circular ring shape component；The rear end outer wall of swelling body cylindrical section is machined with and locks
The external screw thread that ring internal thread hole matches；
Each bulk-breaking of expansion sleeve by housing elastic ring at circular ring shape component, each bulk-breaking front end of expansion sleeve
Guide pin is inserted into respectively in each guide groove of retaining ring rear end face；The front end of swelling body sequentially passes through expansion sleeve and retaining ring,
And it is threadedly coupled by the external screw thread of swelling body cylindrical section rear end outer wall with retaining ring.
In use, swelling body conical section one end by clamping tool is inside, it is inserted into the inner wall of cylindrical member to be clamped, holds lock
Tight ring, and swelling body is rotated, move swelling body axially outward relative to retaining ring.It is swollen while axial movement with swelling body
The male cone (strobilus masculinus) of tight body back segment conical section squeezes expansion sleeve, makes each bulk-breaking of expansion sleeve along each guide groove of retaining ring rear end face
Radial outward dilations realize the clamping to cylindrical member.
The utility model has the advantages that
The clamping tool of the utility model, it is simple structure and convenient processing, easy to operate, it can fast implement to thin-wall tube-shaped
The reliable grip of part, pinching deformation is small, ensure that the machining accuracy of product, improves processing efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model clamping tool；
In figure, 1- expansion sleeve；2- retaining ring；3- swelling body；4- elastic ring.
Specific embodiment
The content of the utility model is further described with reference to the accompanying drawings and examples.
Embodiment
